Problem: Fruit flies with shibire mutations become paralyzed at high temperatures (e.g., 31 °C). Thus far, shibire mutations have been single amino acid substitutions in dynamin, which plays a key role in endocytosis of a neurotransmitter receptor to fine-tune the action of the receptor. A scientist discovers a new mutant fly, which has a shibire phenotype, however, has no mutation in dynamin. What genes should the scientist sequence next to find the mutation that is causing temperature-sensitive paralysis? In other words, select proteins listed below that, when mutated, could cause a shibire phenotype. Select all that apply. Question options: AP3 ARF1 AP1 Clathrin ARF6 AP2
